They feel fast in the bunch, shrug off debris on chip seal, and mount cleanly with standard tubes."Build your road setup the smart way with the Corsa N. EXT G2. 0 Clincher Tire 2-Pack. This matched pair blends low rolling resistance with confident cornering and high mileage manners, so you can cover intervals, fondos, and weekend races without juggling tire choices.
